The three different polyimide films use in General Electrical high density interconnects have been characterized in terms of their out-of-plane and in-plane coefficient of thermal expansion. Glass transition temperature, storage modulus loss factor, and stress-strain and creep behavior, as a function of temperature and as appropriate, deformation rate. In addition, this paper discusses failure mechanisms of Kapton and ULTEM films in tensile tests.
